Description

Technical Field

[0001] This utility model relates to the technical field of steel wire production equipment, specifically a counting and winding device for a wire drawing machine. Background Technology

[0002] Wire drawing machines are key pieces of equipment in the steel wire production process, used to reduce the diameter and increase the length of steel wire through progressive drawing to achieve predetermined dimensions and mechanical properties. The winding mechanism, as the terminal part of the wire drawing machine, is responsible for winding and collecting the drawn steel wire, neatly and tightly winding the finished wire onto the take-up roller for storage, transportation, and subsequent processing. In existing wire drawing machine winding mechanisms, the take-up roller is typically driven by a motor and may be equipped with a guiding structure (such as a wire guide) to achieve winding neatness, as exemplified by the winding device for a wire drawing machine disclosed in patent publication number CN118950742A. However, in actual production management and process control, besides ensuring the winding mechanism completes basic winding operations, knowing the actual length or approximate weight of the wire wound on the take-up roller is also crucial. This helps control fixed-length winding, avoid over-winding or under-winding, and achieve production parameter traceability. Since the wire drawing specifications (diameter) are known, the winding length can be calculated by measuring the number of rotations of the take-up roller, thus allowing for the estimation of the finished product weight. Although some counting schemes for winding mechanisms have been proposed in existing technologies, they still have significant shortcomings, mainly in the following aspects: Firstly, mechanical counting structures are typically used, which are difficult to guarantee in terms of counting accuracy and are prone to damage. For example, patent CN117066303A discloses a take-up mechanism for a cable drawing machine, which includes a gear-meshing counting structure. The number of rotations of the take-up roller can be read by a pointer connected to the counting gear. However, this mechanical transmission method has disadvantages such as easy wear and slippage, and significant counting deviations can occur after long-term use, requiring frequent maintenance and calibration. Secondly, most equipment is only equipped with a cumulative counting module and lacks real-time display functionality. Operators cannot monitor the winding progress in real time and must manually read the counter value after stopping the machine. This leads to a lag in obtaining the number of rotations, which can easily result in over-winding leading to loose wire or under-winding requiring secondary winding, affecting production continuity. Third, the existing counting structure and guiding structure are independent and cannot achieve coordinated control. Specifically, the rotation speed of the take-up roller is not constant during production and will vary due to start-up, shutdown, gear shifting, or wire diameter. However, most current take-up mechanisms use a fixed speed or simple segmented speed for the guiding structure to move. Therefore, when the rotation speed of the take-up roller changes, the moving speed of the guiding structure cannot be adjusted synchronously, which can easily lead to excessively sparse or dense wire arrangement, or even overlapping or messy wire arrangement, requiring manual intervention and adjustment, thus affecting the take-up quality and production efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a counting and winding device for a wire drawing machine, in order to solve the problems mentioned in the background art, that the existing wire drawing machine winding mechanism cannot efficiently count the number of rotations of the winding roller and cannot coordinately control the guide speed.

[0004] This utility model is achieved using the following technical solution: A counting and winding device for a wire drawing machine includes a frame, a take-up roller, a guide assembly, and a drive mechanism. The drive mechanism includes a drive mechanism I for driving the take-up roller to rotate and a drive mechanism II for driving the guide assembly to reciprocate. The take-up roller is detachably connected to a transmission shaft in drive mechanism I. The guide assembly is located on one side of the take-up roller. The device also includes a magnetic grating ring, a magnetic grating reading head, a controller, and a display operation panel. The magnetic grating ring is interference-fitted onto the transmission shaft, and the sensing end of the magnetic grating reading head faces the outer circumferential surface of the magnetic grating ring. The controller is electrically connected to the magnetic grating reading head, the display operation panel, and drive mechanism II.

[0005] The winding mechanism provided by this utility model, by setting up a magnetic grating ring, a magnetic grating reading head, and a controller, realizes the detection of the number of rotations of the drive shaft, and thus realizes the real-time detection of the number of rotations of the take-up roller. The magnetic grating ring and the magnetic grating reading head work in a non-contact manner based on the principle of magnetic induction, which can avoid the wear and slippage that often occur in mechanical counting structures, and has high counting accuracy. The display panel can display the number of rotations in real time under the control of the controller, so that the operator can keep track of the winding progress in real time, and thus effectively avoid over-winding or under-winding. The controller can further calculate the winding speed of the take-up roller based on the number of rotations, and then adjust the working parameters of the drive mechanism II according to the winding speed, so that the moving speed of the guide component can keep in sync with the winding speed of the take-up roller, that is, to realize the closed-loop linkage control of rotational winding and wire guiding, which can effectively improve the uniformity of wire laying and avoid the problems of overlapping and messy wires.

[0006] Furthermore, a limiting ring is provided on each side of the magnetic grid ring. By providing the limiting ring, axial movement of the magnetic grid ring can be prevented.

[0007] Furthermore, the frame includes two protective housings, with the take-up roller located between the two housings, and the magnetic grating ring and magnetic grating reading head located inside one of the protective housings. By placing the magnetic grating ring and magnetic grating reading head inside the protective housing, it can protect against oil, dust, moisture, and other contaminants in the working environment, helping to maintain operational reliability and measurement accuracy.

[0008] Furthermore, the magnetic grating reading head is mounted inside one of the protective housings via a fixing bracket with damping pads. By incorporating damping pads, the impact of vibration can be reduced, thereby ensuring the detection stability of the magnetic grating reading head.

[0009] Furthermore, a magnetic shielding cover is provided on the outer side of the magnetic grating ring and the magnetic grating reading head, and the magnetic shielding cover is grounded through a grounding wire. By setting the magnetic shielding cover, the sensing area of ​​the magnetic grating ring and the magnetic grating reading head can be covered, effectively shielding against electromagnetic interference generated by motors, etc.

[0010] Furthermore, a display operation panel is provided on the outer surface of one of the protective housings. The display operation panel includes a panel base, on which a display screen is provided. The display screen is electrically connected to the display driver module built into the controller.

[0011] Furthermore, the panel base is also provided with a reset button, which is electrically connected to the reset module built into the controller.

[0012] Furthermore, the controller also incorporates a signal acquisition module, a counting and speed measurement module, and a guidance control module. The signal acquisition module, the guidance control module, and the display driving module are electrically connected to the counting and speed measurement module, respectively. The signal acquisition module is electrically connected to the magnetic grating reading head, and the guidance control module is electrically connected to the drive mechanism II.

[0013] Furthermore, the guide assembly includes a winding reel, a movable seat, and a slide rail; both ends of the slide rail are connected to the frame, the winding reel is rotatably mounted on the movable seat, the movable seat is sleeved on the slide rail and connected to the drive mechanism II, and the drive mechanism II is configured to drive the movable seat to reciprocate along the slide rail.

[0014] The beneficial effects achieved by this utility model are: This invention provides a counting and winding device for a wire drawing machine. By incorporating a magnetic grating ring, a magnetic grating reading head, a controller, and a display panel, it achieves real-time detection and display of the number of rotations of the winding roller. Furthermore, it can coordinately adjust the reciprocating speed of the guide assembly based on the rotational speed of the winding roller. The magnetic grating ring and the magnetic grating reading head operate in a non-contact manner, avoiding the wear and slippage issues commonly found in mechanical counting structures. Therefore, compared to existing wire drawing machine winding mechanisms, this invention effectively improves counting accuracy and stability, allowing operators to monitor the winding progress and avoid over-winding or under-winding. It also achieves closed-loop linkage control between rotary winding and wire guiding to improve wire uniformity, thereby contributing to ensuring production quality, production continuity, and production efficiency.

Figures 1 to 3 It includes a frame, take-up roller 2, guide assembly, drive mechanism, magnetic grating ring 12, magnetic grating reading head 13, controller and display operation panel, specifically: The frame includes a frame and two symmetrically distributed protective housings 1. The take-up roller 2 is detachably installed between the two protective housings 1. The guide assembly is installed on the frame on one side of the take-up roller 2. The guide assembly includes a winding reel 5, two movable seats 7, two parallel slide rails 6, a limit rod 8, and two limit switches 9. The two slide rails 6 and the limit rod 8 are fixedly connected to the frame at both ends, and the limit rod 8 is located on one side of the parallel slide rails 6. The winding reel 5 is rotatably installed on the two movable seats 7, which are connected and respectively fitted onto the two slide rails 6. The two limit switches 9 are respectively installed at both ends of the limit rod 8 through a screw connection structure, and both limit switches 9 face the movable seats 7 for detection.

[0018] The drive mechanism includes drive mechanism I for driving the take-up roller 2 to rotate and drive mechanism II for driving the guide assembly to reciprocate. Drive mechanism I includes a motor, a transmission assembly (which may be a belt drive assembly, a chain drive assembly, etc., selected by those skilled in the art according to the actual situation) and a drive shaft 10. The drive shaft 10 passes through the inside of the take-up roller 2, and both ends of the take-up roller 2 are detachably connected to the drive shaft 10 through flanges. Drive mechanism II includes a servo motor and a rack and pinion drive assembly. The rack in the rack and pinion drive assembly is fixedly connected to the bottom of one of the movable seats 7.

[0019] The motor in drive mechanism I is located inside one of the protective housings 1. The magnetic grating ring 12 is mounted on the drive shaft 10. Specifically, in this embodiment, the magnetic grating ring 12 is made of neodymium iron boron permanent magnet material, with an outer circumference covered by a 304 stainless steel shell, and has 32 pole pairs (64 poles are optional in other embodiments). The inner diameter of the magnetic grating ring 12 is interference-fitted with the outer diameter of the drive shaft 10, and is mounted on the drive shaft 10 portion inside the protective housing 1 using anaerobic adhesive. Aluminum alloy retaining rings 15 are added to both sides of the ring. The magnetic grating reading head 13 is an industrial-grade magnetic grating reading head (e.g., Sony Magnescale SR138), mounted inside the protective housing 1 via a fixing bracket 14 with damping pads 16 (located between the bottom of the fixing bracket 14 and the inner surface of the protective housing 1), with its sensing end facing the outer circumferential surface of the magnetic grating ring 12. The outer side of the magnetic grating ring and the magnetic grating reading head is covered with a permalloy magnetic shield 11. The magnetic shield 11 has an opening for the drive shaft 10 to pass through, and it is grounded through a grounding wire with a grounding resistance ≤1Ω.

The guide control module is electrically connected to the servo motor in the drive mechanism II. The zeroing / reset module is electrically connected to the zeroing / reset button.

[0021] Based on the above structure, after the winding mechanism starts working, the magnetic grating ring 12 will rotate with the drive shaft 10. The magnetic poles evenly and alternately distributed along the circumference of the magnetic grating ring 12 will alternately pass over the magnetic grating reading head 13. Therefore, the magnetic grating reading head 13 will detect the magnetic field of alternating magnetic poles and send the detection signal to the controller. After processing the signal and performing corresponding calculations, the controller obtains the number of rotations and rotation speed of the winding roller. Then, the controller links the display screen 4 to display the number of rotations of the winding roller in real time, and links the servo motor in the drive mechanism II based on the rotation speed to adjust the reciprocating movement rate of the guide component accordingly.

Therefore, they will not be elaborated on in this article.

This utility model is not limited to the above examples, and all equivalent changes and improvements made by those skilled in the art within the scope of this utility model should be included in the patent coverage of this utility model.
